Description of Prepainted Rolled steel Coil for Construction Roofing
Prepainted Rolled steel Coil is a kind of coated steel coil/sheet. With the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. In its coating, Al accounts for about 55%, Si 1.6%, while the remaining is Zn. Aluminum zinc coils enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative.
Main Feature of Prepainted Rolled steel Coil for Construction Roofing
1.Corrosion resistance: It mainly depends on the aluminum protection. When the zinc being worn, the aluminum will form a dense layer of aluminum oxide, resist corrosion material to prevent further corrosion inside.
2. Heat resistance: Aluminum zinc alloy steel sheet has excellent heat resistance, can withstand high temperatures over 300 centigrade, and is similar with aluminized steel high temperature oxidation resistance. It often used in chimney pipes, ovens, fluorescent lighting device and the device cover.
3. Heat reflective: Galvanized steel plate heat-reflective high rate is twice as galvanized steel, often used to make insulation materials.
4. Economy: Because density of 55% AL-Zn is smaller than the density of Zn, so in the same weight and thickness of Galvanized zinc layer, aluminum-zinc steel plate is larger area more than 3% of galvanized steel sheet.
Applications of Prepainted Rolled steel Coil for Construction Roofing
1. Construction and building: roofing; ventilating duct; handrail; partition panel;etc.
2. Electric appliance: refrigerator; washing machine; refrigerator; DVD;etc.
3.Transportation: oil tank; road sign; etc.
4.Agriculture:barn; etc.
5.Others:vending machine; game machine; etc.

- Q: How are steel coils inspected for coil weight accuracy?
- Steel coils are inspected for coil weight accuracy through the use of weighing scales or load cells. These devices are placed beneath the coil during the inspection process to accurately measure its weight.
- Q: What is the role of steel coils in the manufacturing of appliances?
- Steel coils are used in the manufacturing of appliances to provide strength, durability, and structural integrity to the appliance components. They serve as the foundation for various parts, such as the body, frame, and internal structures, ensuring stability and support. Steel coils also contribute to the overall performance and lifespan of appliances by withstanding high temperatures, corrosion, and mechanical stress.
- Q: How is the critical temperature of structural steel affected by fireproofing? What temperatures can fireproofed structural steel withstand?
- I didn't know they fire proofed steel. Usally they would just use a steel with a higher melting point.
- Q: How are steel coils used in the production of steel drums?
- Steel coils are used in the production of steel drums as they are unrolled and shaped into cylindrical forms to create the body of the drum. These coils are cut, welded, and sealed to form a solid and durable structure, which serves as a container for storing and transporting various materials such as liquids, chemicals, and even food products.
- Q: Why is the selection of steel building erector of extreme importance while starting a new steel building project?
- Because if the beaming is screwed up, everything in the building is at risk. Also, if the erector runs late, everything else is delayed. An incompetent erector can actually cause damage to the beams [especially if inadequate bracing leads to collapse] and getting new ones can severely delay the project.
- Q: What are the common surface treatments for steel coils?
- The common surface treatments for steel coils include galvanizing, painting, and coating with protective films.
- Q: How are steel coils processed for edge trimming or conditioning?
- Steel coils are processed for edge trimming or conditioning through a series of mechanical and/or thermal methods. The coils are first uncoiled and then passed through a slitting machine to cut them into narrower strips. The edges of these strips are then trimmed to remove any irregularities or excess material. This can be done through shearing, grinding, or milling processes. Once the edges are trimmed, the coils may undergo further conditioning processes like straightening, leveling, or rewinding to ensure they meet the required specifications.
- Q: What dangers were there for the steel workers in Pittsburgh under Carnegie?
- All manufacturing jobs of that era were incredibly dangerous, even textile work, but steel work was likely the worst. Men would fall into vats of molten metal, be crushed under huge metal bars, hit by cranes, burned by simple contact with any of the red hot pieces of metal flying all around, and most commonly, die from asphyxiation or lung ailments from the constantly burning fires. Heat stroke was a big killer, too. There was virtually no form of compensation, either for injured workers, or, in the case of death, for their families. The Bessemer method, which Carnegie introduced into the US, was hoped to improve conditions...instead, it merely improved output, and Carnegie's factories after 1900 worked 200,000 men, twelve hours a day, on wages that barely kept their families alive.
- Q: How are steel coils used in the manufacturing of tubes?
- Steel coils are used in the manufacturing of tubes by being unwound and fed through a tube mill where they are shaped and welded together to form seamless or welded tubes.
- Q: What are the different types of steel coil handling equipment?
- There are several types of steel coil handling equipment, including coil cars, coil tongs, coil lifters, coil upenders, coil grabbers, and coil transfer cars. These equipment are specifically designed to safely transport, lift, rotate, and transfer steel coils in various industrial settings.
